Patent CA-2442914-A1 (CA)
Inventor: BERGER JAMES M
IPC: B01L9/00
Filed: 2002-04-05
Abstract: L'invention porte sur le criblage à haut rendement de la cristallisation d'un matériau cible qui s'effectue par introduction simultanée d'une solution du matériau cible dans une pluralité de chambres d'un dispositif fluidique microfabriqué. Le dispositif fluidique microfabriqué est ensuite manipulé de façon à faire varier l'état de la solution dans les chambres, ce qui permet d'obtenir simultanément un grand nombre d'environnements de cristallisation. Le contrôle des états modifiés de la solution peut résulter de divers techniques, notamment mais pas exclusivement, le mesurage de volumes de l'agent de cristallisation dans la chambre par exclusion de volume, par piégeage de volumes de l'agent de cristallisation déterminé par les dimensions de la structure microfabriqué ou par injection par un canal transversal de l'échantillon et de l'agent de cristallisation dans un ensemble de jonctions définies par l'intersection de canaux d'écoulement orthogonaux.

Title: Arc fault detector with circuit interrupter
Inventor: BRADLEY ROGER M
IPC: H02H3/44
Filed: 2003-10-03
Abstract: There is here disclosed a method and apparatus for detecting the occurrence of arcing of a conductor by monitoring the current on an AC power line. The signal detected is split and directed along four separate paths to generate four signals leaving separate characteristics which represent the current in the line. A first path is for a signal representative of the current flowing in the line. A second paths is for a signal having a pulse for each occurrence of a positive step change in current that is significant and has a di/dt value above a predetermined value. A third path is for a signal having a pulse for each occurrence of a negative step change in current that is significant and has a di/dt value above a predetermined value. A fourth path is for a signal having a voltage level representative of the broadband noise signal on the line. Using at least one of five different methods in combination with one of three input signals, a reference signal designated as "SINE" is generated. The SINE signal generated in combination with a CURRENT input is used to produce a control waveform "DELTA". DELTA can be represented as a relative value or as an absolute difference between the SINE and the CURRENT. Each occurring half cycle of the DELTA signal is analyzed by, for example, a micro- controller for specific identifiable characteristics found to indicate the presence of arcing. Upon the detection of arcing, an output signal can be generated to activate a circuit interrupting mechanism, sound an audio alarm and/or alert a central monitoring station.
